Note: Heat build-up is the limiting factor in the pumps performance. Operating above or
below the recommended speed range will increase the heat produced and negatively
impact the life of the pump.
Vacuum Relief Valve
The vacuum relief valve should be set at a maximum continuous working vacuum level of 20
sea level for optimum pump life and performance.
The working vacuum level should be dec 1,000ft of elevation.
To set the vacuum relief valve:
Unscrew and remove the Blue Dust Cap;
Loosen the Lock Nut and adjust the vacuum level by increasing or decreasing spring tension
with the Adjusting Nut; and
When the vacuum level is set retighten the Lock Nut and screw the Blue Dust Cap back on.
The vacuum relief valve setting should be verified by using a quality liquid filled vacuum gauge.
Warning! The vacuum relief valve is not set at the factory.
Pressure Relief Valve
It is recommended to set the pressure relief valve below 15 PSI. This level is adequate in majority of
applications.
For pressure settings above 15 PSI the tank manufacturer should be consulted for recommended
operating pressures.
To set the pressure relief valve consult the manufacturers setup guide.
